The work process of whole device is described below:
When performing the operation, inserting internal after first being closed by the distal jaw assembly 1 of intracavity Endo-GIA, now joint does not turn to, it is straight to keep, it is simple to apparatus inserts and seals, after entering body cavity, distal jaw assembly 1 is opened, and according to actual operation needs, carries out joint course changing control.
In the steering control device of joint, turn to gear piece 11 will rotate with joint steering knob 3.The cylindrical boss 30 turning to right slide block 14 is positioned in the U-type groove 2 25 turning to gear piece 11, and the cylindrical boss 32 of port slide block 13 is positioned in the U-type groove 1 turning to gear piece 11, and initial position is shown in Figure 11.The tip 35 of card article resilience drive block 12 is stuck in the tooth root of the arc teeth portion 29 turning to gear piece 11.The tip 38 of steering connections card article 20 is withstood on the tooth root of arc teeth portion 52 of steering connections 21 by steering connections card article 20 under the spring effect of spring 19, the rotation of restriction steering connections 21, namely limits the rotation in joint, simultaneously lockable angle.
nullGear piece 11 is turned to when rotating counterclockwise by Figure 12 direction of arrow with hands，The arc teeth portion 29 turning to gear piece 11 can be applied to the thrust that the tip 35 of card article resilience drive block 12 is certain，Card article resilience drive block 12 is made to retreat (in Figure 12 direction) to the right，Hook sheet 17 by card article rollback and steering connections card article 20 is pulled back (in Figure 12 direction) to the right，Steering connections card article 20 and steering connections 21 is made to disengage，When turning to gear piece 11 to rotate α angle，Turn to the U-type groove 2 25 of gear piece 11、The sidewall of U-type groove 1 just withstands the cylindrical boss 30 turning to right slide block 14、The cylindrical boss 32 of port slide block 13，Gear piece 11 is turned to utilize U-type groove 1、The sidewall of U-type groove 2 25 is applied to port slide block 13 thrust，It is applied to and turns to right slide block 14 pulling force，Port hooks sheet 15 and turns to right hook sheet 16 to be subject to port slide block 13、The pretightning force of right slide block 14 is turned to not move，As shown in Figure 12 and Figure 13 I partial enlarged drawing.With reference to Figure 14, it is rotated further joint steering knob 3, now steering connections 21 is subject to the thrust (in Figure 14 B direction) in port hook sheet 15 direction and turns to the pulling force (in Figure 14 A direction) of right hook sheet 16, steering connections 21 rotates counterclockwise and (it should be noted that, port hooks sheet 15 and turns to right hook sheet 16 to be resilient for, thrust is substantially inoperative, mainly pulling force makes steering connections 21 turn to), now the tooth top on steering connections 21 is lived steering connections card article 20 and is made in its tooth root without falling into steering connections 21, as shown in II partial enlargement of Figure 15.If now release joint steering knob 3, port hooks sheet 15 and turns to right hook sheet 16 to lose pretightning force, and now steering connections 21 is by the tooth root being rotated further the tip 38 making steering connections card article 20 and proceeding to steering connections 21, and steering angle is locked in herein.If not discharging joint steering knob 3, the tip 38 of steering connections card article 20 will not snap in the tooth root of steering connections 21 all the time, can realize the continuous rotation in joint.
Port hooks sheet 15 and turns to right hook sheet 16 to be not limited to rigid material to make, it is also possible to be that flexible material is made.When adopting rigid material, port hooks sheet 15 and turns to right hook sheet 16 is elongated structural member.
Rotation by joint steering knob 3, drive the rotation turning to gear piece 11, gear piece 11 profile of tooth is turned to pass through Mechanical Calculation and Analysis, only small can the realization of joint steering knob 3 rotatory force is made to rotate, promote card article resilience drive block 12 rectilinear motion, port hooks sheet 15 and turns to right hook sheet 16 to pull steering connections 21 to rotate, namely joint go to action is realized, when the power being applied to joint steering knob 3 is cancelled, steering connections card article 20 snaps in the tooth root of steering connections 21 under spring force, the rotation of restriction steering connections 21, realize joint steering angle locking, also continuous cradle head steering knob 3 can be realized, realize different joint steering angles.Angle can position, and simple in construction is safe and reliable.
Turning to angle design between the arc teeth portion 29 of gear piece 11 and most advanced and sophisticated 35 to ensure will not self-locking.Between the arc teeth portion 52 of steering connections 21 and most advanced and sophisticated 38 angle design want can self-locking, therefore can realize when joint turns to laborsaving, turn to rear angle lockable.
The above, only to the preferred embodiments of the present invention, is not limited to the present invention, and for a person skilled in the art, the present invention can have various modifications and variations.Every within the scope of the claim restriction of the present invention, any amendment of making, equivalent replacement, improvement etc., all should within protection scope of the present invention.
